## Introduction
The project showcases how to use the Web3 library to interact with an Ethereum smart contract. It includes sample code to connect to a local Ethereum blockchain, subscribe to pending transactions, fetch the creator's address of a smart contract, and listen to the 'Transfer' event and buy the desired `Token` before the targeted `wallet`
## Prerequisites
Before using this project, ensure you have the following prerequisites installed:
- Node.js: [Download Node.js](https://nodejs.org/)
## Installation
1. Clone the repository:
```bash
git clone https://github.com/PrantaDas/mint-an-nft.git
```
2. Change to the project directory:
```bash
cd mint-an-nft
```
3. Install dependencies:
```bash
npm install or yarn
```
## Usage
1. Set up your Ethereum blockchain (e.g., Ganache) and update the WebSocket provider address in the `web3` initialization:
```javascript
const web3 = new Web3('ws://your-ethereum-node-ip:7545');
```
2. Specify the contract address and ABI in the `abi.json` file and update the `.env` file with the contract address and default wallet address.
3. Customize the `wallet` variable with the desired wallet address.
4. Run the script:
```bash
node index.js
```
## Functions
- `getContractCreatorAddress()`: Fetch the creator's address of the smart contract.
- Subscription to pending transactions.
- Logging transaction data and executing the mint function if the transaction is from a specified wallet.
- Subscription to the 'Transfer' event of the smart contract.
## Examples
Check the `examples` directory for usage examples and sample scripts.
